Diablo 12" 14/18TPI Bi-Metal Reciprocating Saw Blades for Medium Metal (25-Pack) are engineered specifically for demanding metal cutting tasks where precision, speed, and blade longevity matter most. Designed to cut metal ranging from 1/16" to 5/16" thick - including rebar, angle iron, cast iron, and steel tube - these Diablo bi-metal recip saw blades deliver professional-grade performance in both corded and cordless reciprocating saws. The 25-pack format keeps job sites well stocked and reduces downtime on heavy metal fabrication, demolition, and structural cutting work.

Key Features

• Full Contact Arched Design - keeps more working teeth engaged within the material at once, producing faster cuts in fewer passes with less heat buildup, resulting in up to 5X longer cutting life compared to standard bi-metal blades.
• Ultra-hardened cutting edge - increases blade durability so the teeth hold their sharpness longer through tough metal cutting applications like cast iron and rebar.
• Dual tooth design with double tooth configuration and small gullets - accelerates material removal and adds extra durability, meaning fewer blade changes and more efficient cutting on medium metal stock.
• 1" oversized demolition blade body - stabilizes the blade during cuts, reducing chatter and vibration for straighter, more controlled passes through metal.
• Perma-SHIELD non-stick coating - protects each blade from heat buildup, preventing gumming and corrosion so blades stay cleaner and last longer in continuous cutting conditions.
• 12" blade length with 14/18 TPI - the variable tooth pitch optimizes chip clearance and cut speed across the 1/16" to 5/16" medium metal thickness range.
• 25-pack quantity - provides a full supply of professional blades to keep productivity high on larger projects without frequent reordering.

Why This Product

• Cutting medium metal with standard bi-metal blades often means frequent blade changes and slow progress - the Full Contact Arched Design addresses this directly by delivering up to 5X longer cutting life, reducing downtime and consumable costs on metal cutting jobs.
• The combination of an oversized blade body and dual tooth configuration makes these blades well suited for demanding cuts through rebar, angle iron, cast iron, and steel tube where blade flex and vibration can compromise accuracy.
• Perma-SHIELD coating keeps blades performing cleanly in conditions where heat and friction cause standard blades to gum up or corrode prematurely, extending the usable life of each blade in the pack.
• The 25-pack format is a practical choice for contractors and production environments cutting medium metal regularly - buying in bulk provides consistent blade supply and cost efficiency across multiple jobs.

Frequently Asked Questions

What metal thicknesses are these Diablo recip saw blades designed to cut?

These blades are specifically designed for medium metal cutting applications ranging from 1/16" to 5/16" thick, covering materials such as rebar, angle iron, cast iron, and steel tube.

What does the 14/18 TPI designation mean on these blades?

The 14/18 TPI (teeth per inch) designation indicates a variable tooth pitch. This dual tooth pitch helps optimize chip clearance and cutting speed across the 1/16" to 5/16" medium metal thickness range, balancing material removal rate with durability.

How does the Full Contact Arched Design improve cutting performance?

The Full Contact Arched Design positions more working teeth in contact with the material at any given moment. This results in faster cuts in fewer passes, reduces heat buildup during cutting, and delivers up to 5X longer cutting life compared to standard bi-metal blades.

Are these blades compatible with cordless reciprocating saws?

Yes, the Diablo DS1214BF25 blades are compatible with both corded reciprocating saws and cordless reciprocating saws, making them flexible for job site use where power access may vary.
